Succinate is a pivotal tricarboxylic acid cycle metabolite but also specifically activates the G- and G-coupled succinate receptor 1 (SUCNR1). Contradictory roles of succinate and succinate-SUCNR1 signaling include reports about its anti- or pro-inflammatory effects. The link between cellular metabolism and localization-dependent SUCNR1 signaling qualifies as a potential cause for the reported conflicts.

Maternal adverse childhood experiences and lifetime experiences of racial discrimination: Associations with current household hardships and intergenerational health.

Soc Sci Med

January 2025

Department of Pediatrics, Chobanian & Avedisian School of Medicine, Boston University, Boston, MA, USA; Department of Health Law, Policy & Management, Boston University School of Public Health, Boston, MA, USA.

Growing evidence shows parents' exposure to adverse childhood experiences (ACEs) and lifetime experiences of racial discrimination (EOD) negatively impacts not only their own health, but also their children's health. ACEs and EOD can be conceptualized as a reflection of shared underlying adversities and structural injustices that manifest in inequitable educational and employment opportunities and differential treatment by public policies and programs that impede parents' capacity to support their families. Therefore, a potentially important, but underexplored, mechanism of effects of parent ACEs and EOD on the next generation is through effects on household material hardships.

The basal ganglia (BG) are an evolutionarily conserved and phylogenetically old set of sub-cortical nuclei that guide action selection, evaluation, and reinforcement. The entopeduncular nucleus (EP) is a major BG output nucleus that contains a population of GABA/glutamate cotransmitting neurons (EP) that specifically target the lateral habenula (LHb) and whose function in behavior remains mysterious. Here, we use a probabilistic switching task that requires an animal to maintain flexible relationships between action selection and evaluation to examine when and how GABA/glutamate cotransmitting neurons contribute to behavior.

Diabetic kidney disease (DKD) is the leading cause of chronic kidney disease (CKD) globally and is associated with an increased risk of developing cardiovascular disease (CVD). DKD management requires a multipronged approach to decrease the progression of CKD and CVD. Mineralocorticoid receptor antagonists (MRAs) added to renin-angiotensin-aldosterone system blockade and sodium-glucose cotransporter 2 inhibitor therapy reduce the incidence of cardiovascular outcomes and progression of CKD.

Previous epidemiologic studies examining thyroid function and chemical exposures have typically focused on a single or a limited number of chemical classes, often neglecting the effects of chemical mixtures. This study addressed this gap by exploring the associations between exposure to hundreds of chemicals and thyroid function using an exposome-wide association study (ExWAS) approach and National Health and Nutrition Examination Survey (NHANES) data. We analyzed data from three NHANES cycles (2007-2008, 2009-2010, 2011-2012), which include measures of thyroid function (free and total triiodothyronine [T3], free and total thyroxine [T4], thyroid-stimulating hormone [TSH]) and chemical biomarker concentrations from 9,082 participants.

Background: The Clinical Genome Resource (ClinGen) is an international collaborative effort between scientists and clinicians, diagnostic and research laboratories as well as the patient community. Using a standardized framework, ClinGen has established guidelines to classify gene-disease relationships as Definitive, Strong, Moderate, and Limited based on available scientific and clinical evidence. When the genetic and functional evidence for a gene-disease relationship has conflicting interpretations or contradictory evidence, they can be Disputed or Refuted.
